DALI examples vocab

Thu May 19 18:04:03 CEST 2016

The plan is to create an RDFa vocabulary and then specify the URI as
an http URL where one can get the machine readable vocabulary
document. I haven't around to that yet so the URI in the DALI document
is the correct one for now. I also haven't thought about whether such
a change in URI is acceptable in a 1.0 -> 1.1 update... we did agree
that TAP could extend the vocabulary so the URI for a TAP-specific
example would be different and maybe we should produce RDFa for the
service-specific vocabularies only.

Thoughts?
